Description Austin MicroLynx SMT (surface mount technology) power modules are non-isolated dc-dc converters that can deliver 5A of output current with full load efficiency of 94.0% at 3.3V output. These modules provide precisely regulated output voltage programmable via external resistor from 0.75Vdc to 3.63Vdc. The open frame construction and small footprint enable designers to develop cost- and space-efficient solutions. Features include remote On/Off and overcurrent protection. TM Advance Data Sheet October 2002 Austin MicroLynxTM SMT Non-isolated dc-dc Power Modules 3.0 – 5.5Vdc Input; 0.75Vdc – 3.63Vdc Output; 5A Output Current Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a time-delay fuse with a maximum rating of 15A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.
